I bought a DJI FC40 a couple of years ago and built a FW450 last year with a 3 axis gimble and gopro. Are the manufacturers cameras as good as a gopro or how do they all rate? what I would really like is to have is a handheld controller with the fpv monitor (phone or tablet) on my controller. My 450 is all DJI. Is it possible to convert my 450 to that type of fpv? it doesn't matter what fc, I will adapt.
